Content API
How content leaves the system.
A content API lets a separate frontend, a mobile app or another service read content over HTTP, which is what makes a CMS usable headless. The API type decides how a frontend asks for data and which client libraries fit. A record carries every API type its documentation describes as built in or provided by an official first-party module. Software with no content of its own, or with an API only through third-party plugins, carries no value here.
2 values in use. 176 records do not record this field. For a further 362 the question does not apply, so there is nothing to record. Defined but unused so far: GROQ — a value with no records is a gap in our coverage, not a statement about the market.
